Progress
So far, we have added extra an obstacle detection system using the ultrasonic sensor and a boost in maneuverability to the car. Earlier, the car would only curve slightly when moving left and right. Now, it stays in place and adjusts directions before moving forward or backward.
After user testing, we have concluded that the car works as it was intended to. The ultrasonic sensor adds the automatic breaking functionality that we wanted to add initially. There are a few problems with the sensor though.
Furthermore, we have also figured out how to use the XBee shield to establish wireless connection between two computers. Although, we ran into a problem here too. We will need to book office hours with the Professor to figure this out.
Challenges
As observed in the video shared above, the car moves forward in intervals. This only happens when the code for the motion sensor is uploaded. We have deduced that this must be because of all the system delays associated with the working of the ultrasonic sensor. Furthermore, we cannot figure out how to connect the Xbee shield to p5js. We figured out how to connect the two components of the shield together, but we cannot properly connect it to p5js and then to Arduino. Solving this issue will mark the end of our project.
